RADIO FREQUENCY RECEIVER HAVING DYNAMIC BANDWIDTH CONTROL AND METHOD OF OPERATION

摘要

A radio frequency receiver ( 102 ) includes at least one amplifier ( 108, 114 and 122 ) for amplifying a signal received by the radio frequency receiver, an automatic gain control system ( 158 ) for controlling a gain of the at least one amplifier, and a direct current offset correction filter ( 142 ) for reducing any direct current component of the signal amplified by the at least one amplifier. The direct current offset correction filter has a bandwidth that is dynamically controlled by a change in the gain of the at least one amplifier. The radio frequency receiver also includes a digital automatic gain control unit ( 150 ) having a bandwidth that is dynamically controlled by the change in the gain of the at least one amplifier.
